Resource Conservation: Fuel

Fuel comes in many forms. Here we look at conserving it while still getting the job done.
Most everything we do requires some form of fuel.

Dictionary.com defines
"fuel" as "an energy source for ...". We will use that loose
definition in this section. Therefore, fuel is the energy
source for all the things that require energy to operate.
We will exclude a few types of fuel for our discussion
but just about anything is fair game.

In particular, we will discuss the conservation of:
Gasoline, batteries, Hydrogen, kerosene, Jet A, Bunker B and
C, Natural Gas, fire wood and wood pellets, coal and many
other forms of fuel.
The more efficient use of these fuels saves money and
is beneficial all around.
